Phase 2: AgentCore Development

Step 1: Agent Implementation

Core Agent Structure:

from bedrock_agentcore.runtime import BedrockAgentCoreApp
from strands import Agent, tool
from strands.models import BedrockModel

# Initialize AgentCore App
app = BedrockAgentCoreApp()

# Initialize Foundation Model
model = BedrockModel(
    model_id="anthropic.claude-3-7-sonnet-20241022-v1:0",
    region="us-east-1"
)

@tool
def store_trade(trade_data: dict) -> dict:
    """Store trade with validation and normalization"""
    # Implementation details...
    pass

@tool
def find_matches(trade_id: str) -> dict:
    """Find potential matches for a trade"""
    # Implementation details...
    pass

# Agent Definitions
ingestion_agent = Agent(
    name="Trade Ingestion Agent",
    model=model,
    tools=[store_trade],
    instructions="""
    You are a trade ingestion specialist responsible for:
    1. Validating trade data integrity
    2. Normalizing data formats
    3. Storing trades with audit trails
    4. Handling validation errors gracefully
    """
)

matching_agent = Agent(
    name="Trade Matching Agent",
    model=model,
    tools=[find_matches],
    instructions="""
    You are a trade matching specialist using:
    1. Deterministic matching for exact matches
    2. Probabilistic matching for fuzzy matches
    3. Confidence-based decision making
    4. Exception creation for unmatched trades
    """
)

@app.entrypoint
def trade_settlement_handler(payload):
    """Main entrypoint for trade settlement operations"""
    operation = payload.get("operation", "status")

    if operation == "ingest":
        return ingestion_agent(payload)
    elif operation == "match":
        return matching_agent(payload)
    else:
        return {"status": "ready", "available_operations": ["ingest", "match"]}

Step 2: Configuration Setup

AgentCore Configuration (.bedrock_agentcore.yaml):

  "identityConfiguration": {
    "type": "COGNITO_USER_POOL",
    "userPoolId": "us-east-1_XXXXXXXXX",
    "clientId": "your-client-id"
  },
  "targetConfiguration": {
    "type": "AGENT_RUNTIME",
    "agentRuntimeArn": "arn:aws:bedrock-agentcore:us-east-1:ACCOUNT:runtime/trade_settlement_system"
